As we posted earlier, Luke Weston from our open source partner Lunar Numbat recently gave a talk at lac2011 (the Linux of Australasia). You can now watch his complete talk online at this link. During his talk Luke gave an update on some of Lunar Numbat's ongoing developments, and in particular, his latest progress on the throttle control avionics and radar altimeter. Lunar Numbat is currently developing hardware for AUSROC 2.5, a sounding rocket of the Australian Space Research Institute (ASRI). After demonstrating the designs on the rocket, space-qualified versions will be developed for use on the White Label Space lunar lander.
